Depends if they know their stuff or not, it’s just not about the TDA5141 d/a chip then there’s a host of other things as well, it has to be implemented right, especially using todays thinking on the I/V (current to voltage) stage after the dac. There has been massive improvements made here, using zero feedback transconductance amps, instead of the usual text book opamps or passive resistors.
I think a good option maybe for you is to get a well reviewed dac that has the TDA1541 in it cheap, here is a big download list for you to look at. Be patient it’s big.
Then get whoever your diyer is to give it a good I/V stage, use this one here I started, your diyer should know how to do it.
